摘要
本文探讨了新锑钼蓝法的加热生成砷锑钼蓝与磷锑钼蓝杂多酸的最佳条件及其组成摩尔比,利用在0.36mol/L硫酸条件下杂多酸吸光度具有加和与在0.51mol/L硫酸条件下砷下显色的特性,提出子在同一显示条件下直接同时测定痕量砷和磷和光度法,此方法能准确,简便和快速地测定水样,饮料和化学试剂中痕量砷和磷。
The optimum condition and the molar ratio in ion-associate Complex has been investigated for color development of arsenoantimomolybdate blue and phosphoantimomolybdate blue heteropoly acid in the simultaneous heat.The absorbance of the two ion-associate complexs have additive property in the condition of 0.36mol/L Sulphurie acid, and arsenoantimomolybdate blue has not developed in the condition of 0.51 mol/L sulphurie acid.The spectrophotometry of antimomolybdate blue in the Water Phase is Presented for the determination of trace amounts of arsenic and PhosphorusoThis method is sensitive, accurate, simple and rapid. As and P in some watse water, chemical reagent and drinks are determind directly by the Proposed method with satisfactory results.
